As shown in the figure = permanent magnet motor 3 (8) also belongs to the inner rotor type permanent magnet motor, which can be used as the driving device of the elevator. The permanent magnet motor 300 is mainly composed of a stator 3〇5, a rotor 37〇 and a bearing 36〇, wherein the bearing 360 connects the stator 305 and the rotor 37〇, and the stator 3〇5 surrounds the turn 370. The remaining permanent magnet motor 300 is used to drive the components of the elevator (such as the Goni wheel, etc.), and can refer to the permanent magnet motor produced by the existing Shanghai Yongda Jiyi Motor Co., Ltd. and the elevator product manufactured by Shanghai Haida Elevator Equipment Co., Ltd. Not much to explain. The tweezer 305 is a ring-shaped object, and its inner peripheral surface includes 24 stator teeth 35 〇, and each of the tweezer teeth 350 includes a stator small tooth 34 〇, but the present invention is limited to this, that is, in other implementations. For example, each of the stator teeth 35G may include one or more stators (the smoke is a stator). In addition, there are sub-slots between the adjacent stator teeth 350 for providing coil windings (10) not shown). The function of ==(4)340 is to modulate the magnetic field. In this embodiment, the stator teeth and the stator teeth 340 form a structure similar to a serpentine shape, but the present invention is not limited thereto, that is, in other embodiments, other shapes are also possible. 201138268 The rotor 370 is also a ring and is fixed to the bearing 360. The outer peripheral surface thereof includes 44 uniformly arranged rotor poles 320. The rotor poles 320 are composed of permanent magnets. Additionally, there is a predetermined air gap 330 between the rotor pole 320 and the top end of the stator pinion 340. Thus, the rotor 370, which rotates with the bearing 360, can rotate along the top end of the stator pinion 340. Note that in this embodiment, the sum of the number of stator teeth 340 (here, 48) is an integral multiple (here, 2 times) of the number of stator slots 310 (here, 24). The number of rotor poles 320 (i.e., permanent magnets) is 44 times equal to the difference between the number of all stator small teeth 340 and the number of pole pairs formed when all coil windings are symmetrically multi-phase current. Further, the stator small teeth 340 have the same length b' in the radial direction, and the ratio of the length b' to the length of the air gap 330 is between 4 and 12. Further, the "scorpion small teeth 340 have the same width & in the circumferential direction, and the ratio of the width to the width c of the rotor pole 320 in the circumferential direction is between 0.8 and 1.2. Here, the stator small tooth 34 〇 width a, the stator small tooth 34 〇 length b, and the rotor pole 32G width e′ of the present embodiment may be different from the width of the small tooth 240 of the foregoing embodiment in accordance with the design requirements. a, the length b of the stator small teeth 240 and the width c' of the rotor pole 220 can be arbitrarily changed. The above are two embodiments of the rotor type permanent magnet motor in the elevator. In other embodiments, the invention is also applicable to an outer rotor type permanent magnet motor. In summary, embodiments of the present invention disclose an integrally formed stator (eg, 'tweezers 2〇5 or 3〇5') that includes stator turns (eg, stator teeth bo or continents and stator teeth) (eg, '^子小齿说或340", wherein the stator teeth are equivalent to the conventional magnetic field modulation block. Thus, the stator of the body shaping solves the problem of fixing the magnetic field modulation block in the known technique of IS1 201138268. Since the permanent magnet motor disclosed in the embodiment of the present invention has only a single air gap 'thus, the torque density is increased, and the torque density of the conventional permanent magnet motor can be doubled.
